I'm wondering what the Android users use for casual stargazing, like identifying or finding objects in the sky in a pinch. I've shopped around for free options, and so far the most complete one I've found is StarTracker. StarTracker shows the locations of manmade satellites and meteor showers as well, which I like, but it, as well as every other free app I've used, isn't detailed enough to have information on other solar system objects -- for example, I haven't been able to pinpoint the comet Wirtanen with any of them. What apps do you use?
